LS50THa/B400R&P10-1 (New standard ≤ 0.35 Å)

50 mm H-alpha solar telescope - B400 blocking filter & Rack & Pinion 10:1 eyepiece holder

This 50 mm H-alpha solar telescope is designed for detailed observation of the solar chromosphere in the H-alpha line (656.28 nm). Thanks to its larger aperture than 40 mm models, it offers a significant gain in resolution and in brightness, This will enable us to reveal the Sun's dynamic phenomena in even greater detail.

This version combines a B400 blocking filter to a Rack & Pinion eyepiece holder with 10:1 fine gearing, for ultra-precise focusing, ideal at high magnification.

H-alpha solar observation

Optimized to isolate the H-alpha band, this system makes it possible to observe :

• Spectacular protuberances at the edge of the disc
• Magnetic filaments and structures
• High-contrast fine surface details
• Daily evolution of solar activity

The 50mm aperture improves detail separation and overall image contrast.

B400 blocking filter

Visit blocking filter B400 ensures totally secure solar observation by allowing only the useful H-alpha band to pass through.
